5. Tesorio

Tesorio combines AR collections automation with cash flow forecasting in a way that most standalone AR tools don't attempt. The product is built for finance teams that want one platform handling both collections workflows and forward-looking cash projections, with machine learning used to predict when individual customers will actually pay. If your CFO is asking for cash forecasts alongside AR performance in the same meeting, this is the tool that covers both.

Key features:

• ML-powered payment prediction by customer and invoice, built from historical payment behavior

• AR collections workflow automation with customizable follow-up sequences

• Real-time cash flow forecasting derived directly from live AR data

• Collections performance analytics and team productivity tracking

• ERP integrations including NetSuite, SAP, Oracle, and Workday

• Customer self-service payment portal

• Team performance tracking for collections staff

What users say 

• The combination of AR automation and cash forecasting in one tool is the primary reason cited for choosing Tesorio: teams that previously ran collections in one tool and cash forecasting in spreadsheets report meaningful consolidation

• ML payment predictions are highlighted as useful for weekly prioritization decisions, helping teams focus on the accounts most likely to create cash timing problems

• Finance leaders specifically cite the ability to present AR performance and cash positioning in one view as a differentiator in board and exec reporting

Where it falls short:

• ERP sync has latency issues: if your ERP doesn't push data to Tesorio in real time, the collections queue won't reflect your current AR state

• Collaboration tools are finance-centric, making it harder to loop in customer success or sales on collections conversations without workarounds

• Smaller teams sometimes find the full platform capability exceeds what they can realistically use or configure

Best for: Mid-market to enterprise B2B companies in tech and SaaS where cash flow forecasting is as operationally important as collections management. Particularly strong for CFOs and controllers who need to present both together.

6. Versapay

Versapay is built around a collaborative network model: buyers and suppliers manage invoices through a shared digital workspace rather than the traditional send-invoice-and-chase-email loop. 

The idea is that disputes, short payments, and payment delays get resolved faster when both sides can see the same invoice, leave notes, and process payment in the same place. It's a different philosophy than most AR automation tools and it works well for companies whose customers are willing to engage with a portal.

Key features:

• Collaborative AR network with shared buyer-seller invoice workspace for dispute resolution and payment

• Automated invoice delivery and payment collection across the network

• ERP integration with SAP, Oracle, NetSuite, Microsoft Dynamics, and Sage

• Cash application automation with remittance matching

• Customer self-service payment portal

• Dispute management and resolution tracking workflow

• Collections automation with escalation rules and aging-based prioritization

What users say:

• Finance teams in distribution and manufacturing report faster invoice dispute resolution as the primary benefit: getting a buyer to acknowledge an invoice in a shared workspace changes the collections dynamic compared to email threads

• The shift from email-based AR to a collaborative portal is well-received by companies whose customers actively engage with it

• Onboarding customers onto the network is described as straightforward when customers are motivated to participate

Where it falls short:

• The UI has been flagged as dated in multiple reviews, with the interface feeling less modern than newer AR tools in the same price range

• Customer support quality is inconsistent: users report slow response times and difficulty resolving technical issues

• Payment limits create friction for high-value transactions, which is a meaningful problem for companies running large B2B invoices

• The collaborative model only delivers value if your customers actually log into the portal, and adoption is not guaranteed

Best for: Mid-market companies in distribution, manufacturing, and wholesale where invoice disputes are a persistent collections problem and customers have enough scale to justify portal onboarding. Less suitable if your customers are unlikely to engage with a third-party payment platform.

7. Kolleno

Kolleno is a newer AR automation platform that has earned the highest G2 rating in this list through strong execution on the fundamentals: workflow automation, ERP sync quality, and a user experience that finance teams consistently describe as intuitive. 

It's built for mid-market companies that want serious accounts receivable management capability without a lengthy implementation cycle. The AI copilot feature, which surfaces customer-level payment context before a collections call or follow-up email, is a differentiator you won't find in most tools at this price point.

Key features:

• Customizable collections workflow automation per customer segment with AI-assisted communication drafting

• AI copilot providing customer-level payment insights and context before outreach

• Real-time ERP and CRM sync with Xero, QuickBooks, NetSuite, Sage, HubSpot, and Salesforce

• Customer payment portal for self-service invoice access and payment

• AR analytics and DSO reporting dashboard

• Mobile app for AR portfolio visibility on the go

• Multilingual workflow support (with noted limitations)

What users say

• Users report an average 32% DSO reduction after implementation

• Customer support responsiveness is cited repeatedly as a competitive advantage: reviewers describe getting real answers quickly, which stands out in a category where support quality is a common complaint

• The AI copilot, which pulls up customer payment history and account context before outreach, is called out as a practical differentiator for collections conversations

• Setup is described as straightforward, with teams able to configure workflows without extensive technical support

Where it falls short:

• Multilingual workflow templates are limited, which matters for companies with customers across multiple regions who need localized collections communications

• The mobile app has gaps in functionality compared to the desktop experience, so teams relying on mobile for AR management will find it incomplete

• Several enterprise reviewers note the platform may not scale to meet the complexity requirements of very large organizations with multi-entity structures

Best for: Mid-market B2B companies (100 to 1,000 active customers) across SaaS, professional services, and tech that want fast implementation and responsive support. Best fit for companies operating primarily in English-speaking markets.

8. Chaser

Chaser is an AR collections tool built specifically around credit control and invoice follow-up for SMB and lower mid-market companies. It plugs into Xero or QuickBooks and automates payment reminders with enough personalization to avoid making your customers feel like they're receiving automated dunning notices. 

The product has won industry awards for credit management, and the user base is largely service businesses and agencies where the relationship side of collections matters as much as the process side.

Key features:

• Automated payment reminder sequences with personalization options to maintain customer relationship tone

• Collections workflow with phone call scheduling, debtor interaction logging, and follow-up task assignment

• CRM integrations with HubSpot, Salesforce, and Zoho

• Credit checking and risk scoring per customer

• Cash flow forecasting built from invoice and payment data

• Customer payment portal with multiple payment methods

• SMS and WhatsApp reminder options alongside email

• Full debtor communication history tracking per invoice

What users say 

• Chaser reports users get paid 54 days sooner and save 15+ hours per week on accounts receivable tasks, with DSO reduced by over 75%. These are company-published figures, but independent Capterra reviewers consistently describe meaningful time savings after switching from purely manual follow-up processes

• The Xero integration is specifically praised for seamless setup and reliable sync

• The ability to see whether a customer opened a reminder email before following up by phone is highlighted as a practically useful tactic for collections timing

• Teams running high invoice volumes report that automating the routine follow-up frees them to focus on the accounts that actually need judgment calls

Where it falls short:

• Email deliverability has become a documented issue: outbound reminders now show 'mail-srv1.com' in the sender information rather than the company's own domain, making automated emails look like third-party collection notices to recipients and reducing response rates

• Advanced email automation is an additional cost beyond the base plan

• Feature requests go unaddressed for extended periods: reviewers flag missing functionality such as custom tags and response-based templates that haven't been shipped despite user requests

• The product is tightly coupled to Xero and QuickBooks, limiting fit for companies on other accounting systems

Best for: SMB to lower mid-market service businesses with 20 to 200 active customers running Xero or QuickBooks. Particularly strong for professional services firms and agencies where maintaining customer relationships during collections is as important as the follow-up itself.

9. Bill.com (BILL)

Bill.com is primarily an accounts payable automation platform that added AR functionality. It's used by hundreds of thousands of small businesses and is one of the most recognized names in SMB finance software. 

The AR module handles invoice creation, payment collection, and basic payment reminders. It is not a collections management platform, and you'll feel that boundary quickly if AR is your primary operational problem rather than AP.

Key features:

• Invoice creation and multi-channel delivery

• Automated basic payment reminders

• Customer self-service payment portal

• ACH and card payment acceptance

• Integration with QuickBooks, Xero, NetSuite, and Sage Intacct

• Basic AR aging reporting

• Accounts payable automation (the core product)

• Corporate card management via BILL Spend and Expense

• Team plan pricing at $55 per user per month for combined AP and AR

What users say

• Small business owners and accounting firms rate ease of use highly and cite time savings on basic invoicing workflows

• QuickBooks integration is the most frequently mentioned reason teams stay on the platform: it works reliably and requires minimal configuration

• For companies running basic invoicing with straightforward payment collection, the product does what it says

Where it falls short:

• Bill.com is better at AP than AR, and not by a small margin. The AR module lacks the collections workflow depth you'd get from a purpose-built accounts receivable software: no meaningful dunning customization, no dispute management, no customer segmentation for collections, no payment prediction

• If your AR challenge is operational, meaning you have volume, varied customer payment behavior, and an actual collections process to run, Bill.com won't solve it

• Per-seat pricing gets expensive as you add users, and mid-market teams find the cost model harder to justify at scale

Best for: Small businesses and accounting firms that need AP automation as the primary use case and want basic AR invoicing alongside it. Not the right tool if AR is your primary operational challenge and you have more than 100 active customers with varied payment behavior.

10. Quadient AR (formerly YayPay)

Quadient acquired YayPay in 2021 and rebuilt it as Quadient AR. The product is a mid-market to enterprise accounts receivable automation platform focused on ease of use for collections teams. It covers automated dunning, customer payment portals, AI-assisted cash application, and real-time aging dashboards. The NetSuite integration is particularly well-regarded in the user community and stands out compared to peers in the same category.

Key features:

• Automated collections workflows with email, phone task management, and escalation rules

• Customer self-service payment portal with multiple payment methods

• AI-assisted cash application and invoice matching

• Real-time AR aging dashboards with account-level drill-down

• Salesforce CRM integration

• NetSuite and multi-ERP integration

• Credit risk management per customer

• Predictive analytics (available on higher-tier plans)

• Custom reporting and analytics

What users say

• The NetSuite implementation is highlighted across multiple reviews as unusually smooth: onboarding did not require weeks of back-and-forth with implementation consultants, which matters for mid-market companies without dedicated IT resources

• The AR aging dashboard consolidates what used to require multiple tools and exports: one reviewer specifically noted being able to see aging, run reports, send invoices, and contact clients all from a single screen

• Collections teams find the day-to-day interface well-structured for working through outstanding invoices systematically

Where it falls short:

• Batch payment notifications generate interface clutter: when customers pay large sets of invoices together, the system creates a separate notification per invoice rather than grouping them

• Reporting customization is described as rigid for non-standard data slices. Teams needing custom reporting views beyond standard templates will find the options limited

• Predictive analytics and flexible workflow rules are gated behind higher-tier plans, meaning the most differentiated capabilities aren't available at entry-level pricing

• Load times are flagged in multiple reviews as slow when searching within large customer lists

Best for: Mid-market to enterprise B2B companies (particularly NetSuite shops) in SaaS, distribution, and professional services that want a well-structured collections tool with real-time auguring visibility. Good fit when your team needs clean AR dashboards without heavy reporting customization requirements.

How do you choose the right accounts receivable software for your business?

The honest answer is that most teams buy the wrong AR software. Not because the tools are bad. Because the evaluation starts at the feature list instead of the operational reality. I've seen finance teams spend six months evaluating platforms, sign a contract, and then discover that the thing they actually needed, whether it was a specific ERP integration or a way to handle contract amendments mid-cycle, was either unavailable or locked behind a higher-priced plan.

So here's how I'd actually approach this. The first filter isn't features. It's scale. Then it's industry. Then it's the specific questions nobody asks until the contract is already signed.

1. Does AR software choice change by company size?

Yes, significantly. The gap between what a 40-person company needs and what a 4,000-person company needs isn't just about invoice volume. It's about operational structure, ERP complexity, and who on your team is actually running collections day to day.

• Under 100 active customers

I've talked to finance leads at early-stage B2B companies who bought Chaser or Upflow and then couldn't get the team to actually use the workflows they configured. The tool works but the discipline doesn't.

If your AR is this small, your real need is structure before software. A lightweight tool that plugs into QuickBooks or Xero, sends automated reminders, and keeps a clean aging view is more than enough.

The question to ask: can this tool go live in a week without IT involvement? If the answer is no, it's already overkill.

• 50 to 500 active customers

This is where things break. 50 customers on varied net terms, a mix of enterprise and SMB accounts, some in dispute, some on payment plans someone negotiated and didn't document. At this scale, manual follow-up fails because the volume exceeds one person's bandwidth, and judgment calls start getting skipped because there's no triage.

I'd argue this is the most important segment to get right. Companies here have enough complexity to need real AR automation software but enough flexibility to still choose the right tool rather than the default. The Hackett Group found that top-quartile performers at this scale hit 28 days DSO versus a median of 46, a gap worth roughly $1M to $3M in working capital depending on your revenue run rate. (Source: The Hackett Group)

At this tier, Upflow, Kolleno, and Ferry are worth evaluating. What you're looking for: configurable dunning workflows per customer type, clean ERP sync without a lag, and shared visibility across AR and customer success. The last one matters more than people admit. Half the disputed invoices I've seen sit unresolved for 60+ days not because nobody chased them, but because AR didn't know a customer success conversation was already happening.

• 500+ active customers or $50M+ in AR volume

At this point the evaluation criteria changes. You're not asking "does it work?" You're asking "does it scale, and who maintains it?"

Enterprise AR automation means something specific: cash application quality at volume, deductions management, multi-entity support, and a support model that doesn't leave your team waiting 72 hours when something breaks during close. HighRadius and Billtrust are built for this tier. The trade-off is implementation time. If you're not prepared for a 6-month rollout and internal change management, you'll buy enterprise software and run it at 40% of its capability.

The stat that focuses on this decision: AR automation reduces DSO by 15 to 30% on average across industries, but enterprise platforms specifically show 30 to 40% improvement over 12 months once fully adopted. (Source: Tesorio Blog) That 10-percentage-point gap between "somewhat implemented" and "fully adopted" is where most enterprise AR software goes to die.

2. Does the industry change which AR software you should buy?

More than most software buyers account for. The accounts receivable problems in SaaS look nothing like the problems in manufacturing, and what works for a 200-person professional services firm will actively frustrate a distribution company billing on purchase orders.

• SaaS and technology companies

SaaS companies have an AR problem that's structurally different from everyone else on this list. The billing model is the complexity. Usage-based contracts, mid-cycle amendments, seat expansions, annual commitments billed quarterly, customer-specific pricing negotiated by sales and loosely captured in a CRM: none of that is straightforward invoicing. The invoice isn't the problem. Building the right invoice from the right contract terms is.

Median DSO for SaaS sits at 35 days, which sounds clean until you look at individual accounts. Enterprise contracts that are technically net 30 but functionally net 60 because of procurement cycles. Sales reps promised extended terms that finance never agreed to. Revenue recognition that needs to match against invoiced amounts at close. The downstream problems from a bad billing process hit harder in SaaS because the models are more complex and the audit requirements are more demanding. (Source: CreditPulse DSO Benchmarks)

For SaaS: the AR software needs to handle the billing model, not just the invoice. Tools that start from contracts rather than line items (Ferry is the clear example) have a structural advantage here because the invoice accuracy problem gets solved at the source. Upflow and Tesorio work well at the upper mid-market where the billing is more straightforward and the primary need is collections visibility and cash forecasting.

One VP of Finance at a B2B software company put it this way: "We weren't slow at collections. We were slow at figuring out what the right number was. By the time we resolved what was owed, the conversation with the customer had already gotten weird." That's a billing problem, not a collections problem. Solve the first one and the second often resolves itself.

• Manufacturing and distribution

Manufacturing has the highest median DSO of any sector I'd recommend AR software for. At 58 days median, best-in-class manufacturers are running at 40 to 45 days and the gap compounds quickly when your average invoice is $100K or more. (Source: CreditPulse DSO Benchmarks)

The structural challenge in manufacturing is that AR doesn't live with finance. It lives across sales, logistics, customer service, and sometimes the plant floor. A payment dispute on a $300K order isn't settled by sending three reminder emails. It requires checking whether the delivery matched the PO, whether there was a short-ship, whether the customer's receiving department signed off. By the time you trace all of that, the invoice is 90 days old and a customer relationship is at risk.

This is why Versapay's network model was designed for manufacturing: getting buyers and sellers on the same invoice view reduces the "we never received it" and "there was a quality issue" response rate that manual AR chasing produces. Billtrust's EDI and multi-channel delivery capabilities also matter here because many manufacturing customers still require specific invoice formats and delivery channels that email-first tools don't handle.

• Professional services

Professional services firms have a billing timing problem more than a collections problem. Milestone billing, time-and-materials invoices, retainers that don't match project phases, work that's done but not yet billed because the engagement manager hasn't submitted hours: the money exists, it just hasn't been invoiced yet. Median DSO in professional services sits at 42 days but drifts significantly higher for firms that don't have a clean process for turning completed work into invoiced amounts quickly. (Source: CreditPulse DSO Benchmarks)

The relationship sensitivity here is real. A law firm, consulting firm, or agency can't send three automated dunning emails to a client they're hoping to renew. The follow-up needs to happen, but it needs to happen with context. Chaser is built specifically for this use case: personalized reminders that maintain relationship tone, with full communication history so whoever makes the call knows exactly what's been said before picking up the phone.

For professional services firms above $10M in revenue with project-based billing across multiple clients: Tesorio's combination of collections automation and cash flow forecasting is worth a serious evaluation. The cash flow prediction piece matters because milestone billing creates lumpier cash flows than subscription businesses, and forecasting from actual billing data rather than revenue projections gives you a materially better number.

3. What questions should you actually ask before buying AR software?

Most demo processes cover the wrong ground. You see the dashboard, watch the dunning workflow run, and leave without answers to the questions that will determine whether the software actually works in your environment.

Here's what I'd ask instead.

• What percentage of decisions still require a human after it runs?

This is the question most vendors won't answer clearly, and it's the most important one. A tool that automates 70% of collections tasks and flags the remaining 30% for human judgment is a different product than one that claims 95% automation but still needs someone to review every exception. Get specific on what the exceptions are and how often they occur in companies similar to yours.

• What does your ERP integration actually look like?

"We integrate with NetSuite" and "we have a native bi-directional NetSuite integration that syncs in real time" are not the same statement. Manual exports, API syncs that run nightly, and native integrations that update on transaction create are three different operational realities. If your team will spend an hour each morning reconciling what the AR tool shows against what the ERP shows, the automation benefit disappears quickly.

• How long does implementation actually take?

Ask for the median go-live time for companies at your size and ERP configuration, not the best-case scenario. Then ask what the common reasons are that implementations run over. 30% of accounting data errors originate from manual data entry during system migrations, and a rushed implementation creates months of cleanup work. (Source: Serrala)

• What does the support model look like after go-live?

Responsive support is cited as a differentiator in Kolleno's G2 reviews specifically because it's rare enough to be noteworthy. Find out whether your company gets a named customer success manager or a support ticket queue, and what the average response time is for non-critical issues during close.

• Can it handle your edge cases?

Every AR operation has edge cases: a customer who always pays in three separate ACH transfers, a contract with a revenue share that affects the invoice amount, a parent company that pays for 12 subsidiaries. Run your three most operationally annoying scenarios through the demo. If the answer to any of them is "that would need to be a manual step," factor that into the evaluation.

The right accounts receivable software isn't the one with the longest feature list. It's the one where 90 days after go-live your team is spending less time on AR than they were before, and your DSO is moving in the right direction. Everything else is a marketing decision.

A note on total cost of ownership

Deloitte's Q4 2025 CFO Signals survey found that 87% of CFOs believe AI will be extremely or very important to finance department operations in 2026, and 60% of US CFOs have moved AR automation to the top of their software priority list. (Source: Serrala, citing Deloitte Q4 2025 CFO Signals) The market is moving fast and vendors know it, which means pricing is less standardized than it used to be.

When you're building the business case, factor in the cost of your current state: collections staff time spent on manual follow-up, borrowing costs from delayed cash collection, and bad debt write-offs from accounts that slipped through the cracks. The Kaplan Group estimates the average B2B company spends $39,406 per year just managing late payments, and that's before you count the opportunity cost of the working capital that's sitting in unpaid invoices. (Source: Kaplan Group) A tool that costs $30K annually and cuts that figure by half pays for itself before the first renewal.

93% of companies report that AR software met or exceeded ROI expectations within the first year of implementation. The math usually works. The question is whether you chose the right tool for your specific operational context. (Source: Resolve Pay)

Final take: what the best AR teams actually have in common

I've spent a lot of time looking at finance operations across companies that run clean AR and ones that don't. The variable that matters most isn't the software. It's whether the team treats AR as a system or as a series of tasks.

Teams running manual AR processes don't just have a slow collections cycle. They have a visibility problem. The CFO doesn't know which customers are trending toward slow pay until they're already 45 days out. Customer success doesn't know an invoice is in dispute until the customer mentions it on a renewal call. Finance doesn't know whether this month's cash position is accurate until close, and by then the information is 30 days stale. The cost isn't just the delayed cash. It's every decision made with incomplete information about the business.

Good accounts receivable software fixes the visibility first. The automation follows from that. Once your team can see the full AR portfolio in real time, can see which accounts are at risk, can see where disputes are sitting, the manual work doesn't disappear overnight but it becomes schedulable and prioritized instead of reactive and urgent.

The data on this is consistent across every source I've read. AR automation reduces DSO by 10 to 33 days depending on implementation maturity. It triples collections productivity on the same headcount. It frees working capital that was already earned but sitting uncollected. 92% of companies that implement it report accelerated cash flow. And for most mid-market companies, the full ROI lands within 9 months of go-live. (Source: Vanson Bourne via Tesorio)

The 10 tools in this guide represent the serious options across the market right now, from SMB-focused tools that plug into Xero in a day to enterprise platforms with multi-ERP cash applications built for $1B+ revenue environments. None of them are perfect. All of them are better than the alternative, which is watching $39,406 in annual late-payment costs compound quietly on a spreadsheet that nobody updates between closes.

The question worth sitting with isn't whether to buy accounts receivable software. That ship sailed when B2B payment terms became a negotiation and customer portfolios grew past 50 accounts. The question is which one fits the company you're actually running, not the one you were last year or the one you're planning to be in 2028.

Pick the tool that solves the problem you have today. You'll know if you made the right call within the first billing cycle.
